How unambiguous was the "Jax is trans" subtext for you?

I need your opinions on this topic because I've been thinking about it since I saw the finale. So before the final episode I expected Jax to turn out to be trans, because of the million clues through the show.

Then when I saw their backstory I was like "oh, so his behavior and the clues weren't refering to Jax being trans, but to Jax being a boy who has a complicated traumatizing past. Including his mom never being satisfied with him, emotionally manipulating him, and forcing this unreasonable level of masculinity on him, etc...

So I let go the "trans Jax" theory, which was a bit of a let down but I liked their deeper backstory, so I was good with it. But later it was confirmed on twitter, and I was really annoyed about, why didn't it happen in the show?

Now I'm watching a reaction about the finale and the youtuber is talking about how he likes it that the show fully confirmed this theory and didn't hold back on it. It confuses me, because the show to give us a full confirmation, but for me the it rather denied the theory, than approved it.

So how did it go for you? Was it really that obvious for you too, or did you interpret it differently as well?
